The order of science teaching ought to be physics-chemistry-biology. This makes sense since it goes in the direction of the simpler to the more complex---recall physics deals with dead matter! Therefore, one can develop a better understanding of what science is and what it is not from learning physics first rather than biology. In biology, the experimental results are often yoked to an evolutionary explanation by burdening the teaching of the experimental aspect of biology, viz. DNA, genetics, etc., which is nonsense.
Physics is more quantitative and so the teaching of physics first would remove that false notion gained by those who start science studies with biology, which is very qualitative, and damages the conception of what science is that if often irreversible. That is why students always balk at physics and say that it is very hard. Of course, physics is difficult if you compare it with biology, which does not put a strain on the brains of our K-12 students.
See the following websites.
More students need more science! (Physics Nobel laureate Leon Lederman is a leader in this effort.)

Physics First in Science Education Reform

Other electives are also available, though not every semester or year such as
Human anatomy, zoology, or botany.

It isn't that students can't take these courses out of sequence ---if the
scheduling allowed for such a thing (& in our small school --it wouldn't) they
could pile up all four science classes in one year if they wanted, but who would
want to do that? So in a practical sense, moving one science class elsewhere
means encouraging the re-scheduling for another for the obvious reason that we
want sciences spread out over their high school years.

gotta go --time for geometry class.
